A radiation detector includes a plurality of scintillators closely arranged two-dimensionally, and a plurality of photoelectron multipliers optically connected to the scintillators. A number of photoelectron multipliers is less than that of the scintillators. A light guide is disposed between the scintillators and the photoelectron multipliers. The light guide is formed of a cured liquid resin and a lattice frame member integrally formed with the cured liquid resin. The lattice frame member forms partition walls in the cured liquid resin to provide compartments therein.

What is claimed is: 1. A radiation detector comprising: a plurality of scintillators closely arranged two-dimensionally, a plurality of photoelectron multipliers optically connected to the scintillators, a number of photoelectron multipliers being less than that of the scintillators, and a light guide disposed between the scintillators and the photoelectron multipliers and formed of a cured liquid resin and a lattice frame member integrally formed with the liquid resin when cured, said lattice frame member forming partition walls in the cured liquid resin to provide compartments therein. 2. A radiation detector as claimed in claim 1, wherein said lattice frame member is formed of at least one material selected from the group consisting of a light reflex material, light blocking material, light transmitting material, and half-mirror. 3. A radiation detector as claimed in claim 1, wherein said lattice frame member is formed of sheet members assembled together to form the partition walls. 4. A radiation detector as claimed in claim 3, wherein each of the sheet members has a first portion where light transmits and a second portion where light does not transmit. 5. A radiation detector as claimed in claim 4, wherein said second portion is formed of a transparent sheet member attached to a layer for blocking light. 6. A method of producing a radiation detector, comprising: preparing a lattice frame member formed of sheet members, disposing the lattice frame member in a liquid resin, hardening the liquid resin with the lattice frame member therein to obtain a light guide, and assembling the liquid guide between a scintillator unit formed of a plurality of scintillators and a photoelectron multiplier unit formed of a plurality of photoelectron multipliers. 7. A method of producing a radiation detector as claimed in claim 6, wherein in forming the liquid guide, the lattice frame member is disposed in a bath, the liquid resin is pored into the bath, and then, the liquid resin is cured for hardening. 8. A method of producing a radiation detector as claimed in claim 6, wherein said sheet member is formed of at least one material selected from the group consisting of a light reflex material, light blocking material, light transmitting material, and half-mirror. 9. A method of producing a radiation detector as claimed in claim 6, wherein each of said sheet members has a first portion where light transmits and a second portion where light does not transmit. 10. A method of producing a radiation detector as claimed in claim 9, wherein said second portion is formed of a transparent sheet member attached to a layer for blocking light.
